Evolution 9 Collection

Features

Grand Seiko Evolution 9 Collection Chronograph GMT

Powered by Caliber 9R86, this Spring Drive chronograph delivers state of the art precision in the measurement of time of day and elapsed time and yet has a quiet and refined aspect that belies its high functionality. The chronograph measures elapsed time up to 12 hours and the seconds hand moves in perfect, continuous and silent glide motion as it does so. The GMT hand allows time in another time zone to be shown exactly and the hour hand can be adjusted to a new zone without compromising the accuracy of the timekeeping. The case is in high intensity titanium, a material that is 30% lighter than steel and yet more impervious to scratches and corrosion. This is a chronograph of true authority.
